Abstract

A nozzle vane segment includes outer (12) and inner band portions with a vane extending therebetween and defining first and second cavities (26, 28) separated by an impingement plate (22) for flowing cooling medium for impingement cooling of nozzle side walls. The side wall (34) of each nozzle segment has an undercut region (44). The impingement plate has an inturned flange (46) with a plurality of openings. Cooling inserts or receptacles (48) having an open end are received in the openings and the base and side walls (53, 51) of the receptacles have apertures (54, 52) for receiving cooling medium from the first cavity and directing the cooling medium for impingement cooling of the side wall of the nozzle segment and a portion of the nozzle wall. <IMAGE>
